13 Claims.

My invention relates to typewriting and like machines and moreparticularly to means for clamping cards or labels to the platen to befed to and past the printing line thereby.

One of the main objects oi the invention is to provide means forclamping and effectively holding round or elliptical labels oi varioussizes as well as rectangular cards or labels on the platen.

A further object of my invention is to provide card and label clampingmeans that are simple in construction, eective in use, and inexpensiveto manufacture and assemble ,and which may be applied to typewriting andlike machines ci various makes.

15 To the above Vand other ends which will hereinafter appear myinvention consists in the features of construction, arrangements Aoiparts, and combinations of devices set forth in the followingdescription and particularly pointed out in the '2 appended claims.

Fig. 6 is a front View showing a -modied form of the construction; and

Fig. 7 is an enlarged, detail, sectional View taken on the line 7-7 ofFig. 2 and looking in the direc- -tion of the arrows at said line.

The invention is shown embodiedin the present instance in a No. 6Remington noiseless machine but may be employed with equal facility inthe Remington No. 7X or noiseless portable as well as other machineswhich employ cylindrical platens. f

v As shown in the present `instance the carriage 10 is mounted oncrossed bearing rollers 1l that travel on xed guide rails, one of whichis indicated at 12 in Fig. 3, to travel from side-to-side of the machineover the top plate.` This carriage supports a cylindrical platen 13 toturn in bearings in end plates 14 on the carriage. The platen isapertured at 15 at different points in the length thereof to receiveheaded clamping members 16, the headed portions' 16a of which arereceived in counter-sunk openings 17 in order that the outer surfaces ofthem'clamping heads may be coincident with the outer surface or" theplaten, as shown in Fig. 1, when the clamping heads are in the normalposition shown in this figure. Each clamping head is provided with abiiurca'ted stem, and as shown in Fig. 3 each stem receives between thearms thereof an arm 18 which projects laterally from and is integralwith a sheet metal bar 19 contained within the platen. A coiledexpansion spring 20 surrounds each arm 18and bears at one end againstthe inner face of the platen and at the other end against the body ofthe bar 19. The effective force of these springs 20 is therefore exertedto maintain the clamping heads in effective position. The arms 18 extendradially of the platen and said arms with the bar'1'9 have a bodilymovement radially of the platen to control the movement of the clampingheads into and out of effective or clamping position.

A spindle 21 extends. into the platen and is mounted centrally thereoffor longitudinal movement. Thus, the spindle is supported at its innerend in a guide 22v fixed v'to the left-hand platen head and containingan expansion spring 23 that bears at one end against the bottom wall ofthe guide opening and at its other end against the inner end of thespindle 21. The other or outer end of the spindle 21 extends through abearing 24: on one ofthe end plates le of the carriage and through acentral opening in the usual nger wheel 25. The outer end of the spindleis provided with a iinger piece 26 by which the spindle may ce shiftedlongitudinally against the force of its spring 23. A screw 27 extendsthrough a tapped opening in the hub ci the right-hand platen head 28 andat its reduced end 29 is received in a spline groove 30 in the spindle.This spline connection between the spindle and platen causes the two toturn together, but affords an independent longitudinal movement of thespindle. The spindle 21 carries a pin 31 in the spline groove 30 whichcoacts with the reduced end 29 oi the screw 27 to limit the outwardandlongitudinal movement of the spindle 21 under the pressure of its spring2 3. When the screw 2'7 is removed los or backed up, the linger wheel25, the member 32 intermediate the linger Wheel and right-hand end plate14 and the spindle 2l may be removed. A reversal of this operationenables the parts to be readily assembled.

IIlhe bar 19 is provided at the ends thereof with integral guide lingers33 that straddle and are disposed on opposite sides of the spindle 21 toaid in guiding the bar 19 and the parts carried thereby radially of theplaten. The spindle 21 is also provided with a plurality of cams locatednear the ends of the bar 19. Each of these cams comprises an inclinedface 34 and a high portion or dwell 35. Inwardly extending projections36 on the bar 19 have inclined faces 37 which coact with the inclinedfaces 34 on the spindle to eiiect a movement or" the bar 19 and theparts carried thereby radially of the platen and against the force ofthe expansion spring 20. When the 1in-- ger piece 26 is moved to theleft as indicated in Fig. 2 the bar 19 and the parts carried therebywill be shifted to the position shown in this iigure thereby bringingthe projections 36 to bear on the high portions or dwells on the spindleso as to hold the clamp in the released position disclosed in thisngure. When pressure on the finger piece 26 is released, the spring 23will shift the spindle to the right, thereby enabling the bar 19 andtheclamping heads to be forced to operative or effective position by thesprings 20.

In assembling the parts the bar 19 is first introduced into the platenwhile a platen head 28 is removed and before the spindle 21 is in place.The springs 20 surround the arms 18 and with the clamping heads 16removed the arms 18 are introduced through the openings 15 in theplaten. An outward pressure is then exerted on the bar 19 to carry themat a considerable distance beyond the outer surface of the platen. Theclainp- I ing heads 16 are then mounted on the arms 19 and connectingpins 38 are driven through registering openings in the bifurcated stemsof the clamping heads and in the associated arms 18 to connect theclamping heads to the arms. Pressure on the bar 19 is then released andthe bar 19 and clamping heads will be shifted by their springs 20 to theFig. 1 position. The removed platen head 28, is then secured in placeand the spindle 21 placed in cooperative relation Vwith the bar 19 andguide 22 as shown in Fig. 1. I prefer to employ intermediate the ends ofthe platen a supporting disk 39 supported by the inner-walls of theplaten and provided with a central bearing opening in which the spindle21 is received to provide a support therefor intermediate its ends.

From an inspection of Figs. 3 and 4 it will be seen that the usual lineindicator and guide 40 is secured by screws 41 to a bracket 42 which inturn is secured by screws 43 to the front iixed guide rail 12 of thecarriage. This guide coacts with a. card as indicated in Fig. 3 tomaintain it snug against the platen in condition to receive the pressureof the type at the printing line.

In the use of the device the card or label may be introduced beneath theclamping heads 16'VL when they are shifted to the Fig. 2 position,either from below or above said clamping heads. The platen is turned ineither direction depending on the character of the card or label engagedby the clamps and whether they are engaged from below or above by theclamping heads. In the use of a rather long rectangular card 44 and asindicated in Figs. 3 and 4 the bott-oni edge of the card is preferablyengaged by the clamping heads and the platen turned in 'ananti-clockwise direction,

as the parts are shown in Fig. 3, to bring the up-l per edge of the cardto the writing line position. When a comparatively small label 45 or 46,for example such as is shown in Fig. 5, is employed, the platen isturned in the same direction so as to carry the. clamped edges of thelabel down and bring the label into proper position with reference tothe printing line. On the other hand as indicated in Figs. 5 and 6, acard 47 may have its leading or upper edge engaged beneath the lowersides of the clamping heads and the platen will then be turned in aclockwise direction, as the parts are shown in Fig. 3, to bring theupper por-A tion of thecard to the printing line. From a con. siderationof Fig. 5 it will be understood that the separate clamping heads 16 arelocated at different distances apart, the two innermost clamping headsbeing arranged close together for engaging at a plurality of points acomparatively small label 45 whereas the distance between one or thesecentrally disposed clamping heads and a terminal clamping head isgreater to enable the clamping heads to effectively cooperate with alarger' sized round label 46. This arrangement is such that any size andshape of label may be clamped at a plurality of points to effectivelyhold the label or card to the platen to be fed to the printing line. Thealigned clamping heads 16 also are eiicective on rectangular cards orlabels, as indicated at 47 in Fig. 5, whether the clamping heads beemployed to clamp the card at the bottom or top edge thereof.

In Fig. 6 I have shown a modified form of construction in which theclamping head 48 is in the nature of a single bar, the head of which isadapted to be received in a correspondingly shaped counter sunk opening48a in the platen and to overlie either the top or bottom edge of acard, like the clamping separate heads 16. The bar 48 is provided withone or more bifurcated extensions in which the arms 18 are received andconnected by pins 38 as in the previously described construction. l'nother words the modified form of construction is similar to thatpreviously described except that a single continuous T-shaped clampingbar is provided in place of the separated clamping heads 16. Thismodified form of construction is intended more particularly for usewhere rectangular cards or labels alone are ernployed.

From certain aspects of the invention I prefer the construction iirstdescribed in that it provides for a wider latitude in effectivelyholding various shapes of cards and labels.

It will be understood that when the card or label clamp is not in use assuch the outer face of each clamping head 16e or the bar48 will be flushwith the outer surface of the platen and will not interfere in anymanner with the use of the platen for ordinary purposes and in which thework sheet or sheets overlie and rest on the clamping heads.

I have shown in Fig. 3 the usual paper deflector 49 and feed rolls 50and 51.

Various changes may be made in the construction and parts thereof may beemployed without 14a others Without departing from my invention as it isdeiined in the accompanying claims.
